Suffering from chronic input oil seal blowouts, rapid drive spline rounding, or a heavy structural rattling echoing across your excavator's flywheel bell housing? Any microscopic twist or concentricity error along the main shaft axis throws your piston rotating group out of alignment, causing internal valve plate friction and costly casing cracks. Protect your primary pressure core from catastrophic structural failure by installing the rugged RITO 720800 hydraulic pump drive shaft.
